The Sandy Bridge-E processor is manufactured on a 32nm process. The LGA2011 package interface supports four channels of DDR3 memory, along with the new X79 single chipset. The new platform will target high-end players and enthusiast users and will replace the existing LGA1366 Core i7-900 series processor and X58+ICH10R chipset.
According to the roadmap, Sandy Bridge-E will launch three models in the fourth quarter of this year and continue into the first half of next year. The highest-end one-of-a-kind version is six cores, clocked at 3.3GHz, has a 15MB cache, and is fully unlocked. Allow free overclocking.
The second six-core clock frequency slightly reduced to 3.2GHz, the cache is reduced to 12MB, overclocking is still no limit.
The third is a quad-core processor, clocked at up to 3.6GHz, comparable to the upcoming quad-core Xeon E3-1290 in the server space, but the cache is further reduced to 10MB, and there is a certain limit to overclocking.
The roadmap also confirmed that the Core i7-2600K and Core i5-2500K will all be upgraded in the third quarter of this year, but will be replaced by the 22nm Ivy Bridge in the first half of next year.
Taiwanese colleague XFastest leaked a road map today, initially revealing specifications of Intel Sandy Bridge-E high-end processor with fever level.
